Unformatted text preview: devices. Most people probably would not object to own one or two pieces of gold treasure. It never hurts to know a little bit about gold. A thin gold foil is 10 cm square and 5 mils in thickness. (one mil is one thousandth of an inch.) The mass of the foil is found to be 24.51 g. (a) Determine the inter-atomic distance (in angstrom) between two nearest-neighbor gold atoms. Note that gold is in an FCC structure. (b) Hypothetically, a phase transformation takes place and the original gold foil transforms from FCC to a crystal structure like silicon. Assume that the new gold foil is still 10cm x 10cm. How thick would be the new gold foil (in centimeter)? Assume that the nearest-neighbor distance of gold does not change after transformation. What would be the foil thickness if instead the lattice constant remains the same before and after transformation?...
